The Texas DPS Criminal Investigations Division (CID) is headed by an assistant director and deputy assistant director and consists of 847 members, including 700 commissioned officers and 147 civilian support personnel. Division personnel are stationed in one of the seven regions throughout the state or at the Headquarters office in Austin.

The CID is divided into five specialized sections:

The Administration Section provides clerical and statistical support, budgetary and procurement oversight, inventory maintenance, personnel management, and information technology support for the division. In addition, the Administration Section oversees the Training Unit, which is responsible for developing and providing relevant and progressive training courses for division personnel.

The Gang Program is responsible for developing proactive strategies and initiatives to reduce the impact of organized crime in the state. Personnel work with local, state, and federal agencies to identify, disrupt, and dismantle prison gangs, street gangs, and other high-threat criminal organizations that pose the greatest danger to our communities.

The Drug Program is charged with the overall direction of the stateís enforcement efforts against drug and human trafficking in Texas. Personnel work with local, state, and federal agencies across the state and nation to identify, investigate, disrupt, and/or dismantle major drug and human trafficking organizations. The Drug Program also conducts investigations into illegal drug laboratories and domestically-grown marijuana; participates in interdiction efforts (land, maritime, and aviation); provides assistance to DPS Highway Patrol; and participates in border operations.

The Special Investigations Program is responsible for investigating, disrupting, and dismantling organized criminal organizations involved in various property crimes, including vehicle theft, cargo theft, fraud, and gaming. Personnel also manage the Texas 10 Most Wanted program; enforce sex offender compliance; assist in enforcing pari-mutuel racing laws and rules at horse and dog tracks throughout the state; and perform background investigations for the Texas Racing Commission, the Texas Lottery Commission, and the Office of the Governor.
